    摘要： It is an object of the present invention to provide an optical waveguide module in which, under the high temperature and high humidity, degradation of characteristics does not occur and which has strength to the oscillation, simple structure, and high reliability. A module unit 30 is formed by bonding a connector 32 provided at one end of a single-optical fiber cable 22 and a connector 31 provided at one end of a ribbon optical fiber cable 21 at both ends of a waveguide substrate 35 having a 1.times.4 branch optical waveguide by an adhesive having light transmission properties. The module unit 30 is provided in a housing 10, and at least a connecting portion between the optical waveguide and the optical fiber cable is covered with the resin contained in the housing 10. The housing 10 is sealed with a cover unit 15, and the single-optical fiber cable 22 and the ribbon optical fiber cable 21 are tightly inserted into a respective hole at end walls of the housing 10 and led out to the outside.

    摘要： The first process for producing an optical fiber coupler includes a first step wherein at least one of the optical fibers to be used is stripped of the coating, a second step in which the bare portion of that optical fiber is heated for a predetermined time to diffuse the dopants, a third step wherein the other optical fibers which have not been heat-treated are stripped of their coating, a fourth step in which the bare portions of all the optical fibers are heated as they are brought into intimate contact, thereby forming a unitary portion, and a fifth step wherein the unitary portion is drawn via heating to form the coupling portion of an optical fiber coupler. The second process for producing an optical fiber coupler includes stripping the coating from at least one optical fiber, fixing the fiber so as to impart an axial stress thereto and then heating the bare portion of the stripped optical fiber thereby thinning the diameter of the heated portion, and then proceeding in the same manner as described with respect to the third through fifth steps of the first embodiment of the present invention. The processes according to the present invention enable a wide-band optical fiber coupler to be easily produced without using optical fibers of different structures but using optical fibers of identical structures.

    摘要： A preform for a polarization retaining optical fiber is produced by making at least two bores symmetrically around a center axis of a preform comprising a core part and a cladding part which surrounds the core part, decreasing a diameter of one end of each bore, or connecting a glass tube to one end of the preform, the glass tube having a part with a smaller inner diameter near its end which is connected to the preform, inserting a first glass rod, a stressing member and a second glass rod in this order from the other end of each bore or from an end of each bore which is remote from the connected glass tube, contacting the first glass rod to the diameter-decreased end of each bore or to the part with a smaller inner diameter of the glass tube, and heating and fusing the second glass rod to the preform.
